The anisotropic properties of pinning effect on a superconducting Nb thin film with triangular arrays of pinning sites, were investigated. A SQUID system was used for the magnetoresistance (MR) measurements. The interaction between flux lines and pinning centers were studied with the help of MR and critical current curves. In the MR and critical current measurements, matching fields were observed. It was found that the pinning potential along the short diagonal created a moving channel of vortices in triangular arrays of defects.
